DEVICE FOR IMPROVING THE COMBUSTION OF FUEL

Description

[0001] The present patent application for industrial invention relates to an improved device for the treatment of fuel taken from a tank through a pump. This device is aimed at being installed in the vicinity of a combustion chamber and determines an improvement of the combustion of the fuels, whether they are in the liquid phase or in the vapour phase, through a double physical action.

[0002] In practice, the fuel driven by a fuel circulating pump through the device is subjected to two physical influences: heat and an intense magnetic field caused by the effect of a powerful electromagnet. As a result of this action, the fuel has a greater fluidity, due to the breakdown of the molecules, such as to facilitate the combustion reaction in the combustion chambers with the effect of producing a greater engine efficiency and a reduction of the polluting emissions.

[0003] In particular, the influence of magnetism on combustion has already been known for some time, since 1846, i.e., since Faraday noticed that a flame, when it was produced in a magnetic field, was brighter than in the absence of the very field.

[0004] More recently, some very simplified devices were mounted on many aircrafts of Italian production and from the Vickers-Terni company. Towards the end of World War II, these devices began to be found in particular on English and American aircrafts, land and sea-going vehicles. In order to be able to explain what was special about this object, we had to wait until the concept of 'electron spin' was introduced in physics during the last century. It was thus understood that if a magnetic field could affect a plasma electron, it could also change the spin of the electrons bound to the atom. From the magnetic point of view, an everyday element, such as hydrogen (H₂) for example, exists in two forms:

• diamagnetic hydrogen (H₂) (with the two atoms with opposite spin) and
• paramagnetic hydrogen (H₂) (with the two atoms with coinciding spin). The latter is highly reactive and unstable, so that it seems to have a self-priming behaviour. This was the reason why only the first type is stored in the tanks of the space missions, and then, shortly before reaching the injectors, it is magnetically pre-treated, becoming highly reactive, enabling the engines to achieve, or at least to get close to, the rated power declared by the manufacturers.

[0005] Devices that operate in this way and that can be grouped into two categories are currently available on the market:

1) Devices with permanent magnets, which have physically two obvious limitations: they guide the magnetism only through a vacuum, or rather the air, and cannot create a heating effect that determines an enhancement of the characteristics for improving the combustion, in particular in cold climate situations.

2) Devices with coils, through which passes a current (solenoids), which produce a limited magnetic field, when propagated through a vacuum, or rather the air.

[0006] DE 197 42 651 describes a device for treating the fuel prior to combustion, according to the preamble of claim 1.

[0007] FR 2,926,606 teaches to arrange a ferromagnetic core within a fuel tank.

[0008] WO 2007/090 218 teaches to arrange coils on the outer surface of a fuel tank.

[0009] The device according to the invention has been designed to greatly enhance the main effect that determines the improvement of the combustion. This effect is the magnetism and is obtained thanks to the installation in the fuel transit chamber of a core of ferromagnetic material.

[0010] This ferromagnetic core is constructed with a screw-shaped rod, in order to provide turbulence to the circulating fluid. As a result of a series of coils through which passes a current, the ferromagnetic core produces a magnetic field of very high intensity, by far higher than the vacuum. In this way the core behaves as a true magnet, adding to the force of the electromagnet.

[0011] Speaking of intensity of the magnetic field, it is useful to think in terms of magnetic flow lines, which move from one pole to another. The higher the number of flow lines, the more intense the magnetic field will be, the more the lines are rectilinear and parallel to each other, the more uniform and intense the field will be. In the ferromagnetic material there are many magnetic particles, otherwise not present in the vacuum.

[0012] These particles, when subjected to the magnetic field, will align with the field itself. Conversely, if there is only air, the field lines make large arcs around the magnet before they reach the other pole. All the lines of force emerging from one pole are however forced to reach the other pole.

[0013] In conclusion, a ferromagnetic core, which is subjected to a magnetic field generated by a coil through which passes a current (solenoid), which becomes an electromagnet (Hopkinson's law), behaves as a true "preferred flow channel".

[0014] The device according to the invention is mounted after a fuel filter, if present, however, as close as possible to the combustion chamber.

[0015] For more clarity on the construction and functionality of the device, reference is made to the attached drawing, which is given only as an illustration and is in no way restrictive, in which:

Figure 1 is an axial cross-sectional view of the device according to the invention.

[0016] With reference to Figure 1 is described the device according to the invention, generally designated by the reference numeral (100). The device (100) comprises an outer container (1), closed at its ends by two caps (2a, 2b) provided with a central hole (20a, 20b).

[0017] A tank (3) comprises an inlet duct (3a) for the entry of the fuel into the tank and an outlet duct (3b) for the exit of the fuel from the tank. The inlet and outlet ducts (3a, 3b) protrude from opposite sides of the tank (3). These inlet and outlet ducts (3a, 3b) are of the type with a reduction, in that they have different diameters depending on the fuel supply pipe installed on the vehicles, usually from 8 mm for cars and vans, 10 mm for trucks.

[0018] The inlet and outlet ducts (3a, 3b) are inserted respectively in the two central holes (20a, 20b) of the two caps, so as to protrude outward from the closed container, to be able to be coupled to the respective fuel-supply tubes (4a, 4b). The fuel is supplied by a pump of the vehicle or plant. In this way the fuel passes through the tank (3).

[0019] The tank (3) is centred within the outer container (1), thanks to the coupling of the two inlet and outlet ducts (3a, 3b) within the two central holes (20a, 20b) of the caps.

[0020] A ferromagnetic core (6) is located inside the tank (3) arranged in axial position. The ferromagnetic core (6) has the form of a screw in order to make the flow of fuel turbulent. The ferromagnetic core (6) is fixed in the tank, in an axial position, by means of two sealing rings (7) provided with holes that allow the fuel to freely flow. The sealing rings (7) have a peripheral edge coupled to the tank and a central portion coupled to the ferromagnetic core (6) so as to maintain the ferromagnetic core (6) in axial position within the tank.

[0021] At least one coil (5) is glued to the outside of the tank (3). Preferably several coils (5) are connected in parallel to each other and supplied with low-voltage current, such as for example a 12V or 24 V supply voltage, which is typical for the batteries of vehicles.

[0022] Optionally two filters (8a, 8b) are arranged in the tank (3), near the inlet duct (3a) and the outlet duct (3b), respectively, of the tank. Each filter (8a, 8b) comprises a metal mesh provided with small holes, which, when the fuel passes through them, cause a fuel spraying. This spraying, combined with a turbulence phenomenon generated by the screw-shaped configuration of the ferromagnetic core (6), places the passing fluid in the best conditions, favouring and enhancing the effects generated by the powerful magnetic field produced by the coils (5).

[0023] The ferromagnetic core (6) behaves like a true magnet, adding to its own magnetic field, also a magnetic field of an electromagnet. (Hopkinson's law).

[0024] In addition, the Joule effect of the device, due to the heating caused by the voltage drop on the electrical windings (5), is recovered in order to heat the fuel within the tank. This is an additional improvement to the capability of fuel combustion. In this case, the filters (8) are used either as sprayers or as thermal bridges between the coils (5) and the core (6), or as direct heat exchangers with the fuel.

[0025] Between the coils (5) and the container (1) is left a gap (9), which is filled by casting a two-component epoxy resin, of the type used to embed the electronic circuits. The epoxy resin perfectly seals the components inside the container (1) and prevents the hum or vibration produced by the coils (5) when they are supplied with current.

[0026] The container (1) is preferably made of metal, in order to dissipate the heat produced by the coils (5). The caps (2a, 2b) are made of aluminium. The tank (3) is made of copper, but can also be made of aluminium

[0027] Ii is important to emphasize that depending on the type of application, which the device is intended for, the tank (3) and, hence, the outer container (1) with the closing caps (2a, 2b), the ferromagnetic core (6), the sealing rings (7), the filters (8a, 8b) and the coils (5) are to be dimensioned proportionally, since the tank (3) will need different diameters depending on the different flow rates of the fuel.
